<div class="refsect1">
<a name="id-1.3.46.8.2.7.5.4"></a><h2>Description</h2>
<p>Defines operator overloads for <span class="emphasis"><em>operator=()</em></span> that each produce an expression instantiated from the <span class="emphasis"><em>expr_template</em></span> expression template. One overload is defined for each of the qualifiers <code class="computeroutput">const &amp;</code>, <code class="computeroutput">&amp;</code>, and <code class="computeroutput">&amp;&amp;</code>. For the lvalue reference overloads, <code class="computeroutput">*this</code> is captured by reference into the resulting expression. For the rvalue reference overload, <code class="computeroutput">*this</code> is moved into the resulting expression.</p>
<p>The <span class="emphasis"><em>rhs</em></span> parameter to each of the defined overloads may be any type, including an expression, except that the overloads are constrained by std::enable_if&lt;&gt; not to conflict with the assignment and move assignement operators. If <span class="emphasis"><em>rhs</em></span> is a non-expression, it is wrapped in a terminal expression.</p>
